Abstract: We investigate wealth distribution on scale-free networks with different consumption strategies. We indicate that nonlinear consumption function can lead to exponential wealth distribution with a power law tail in accordance with empirical data. In addition, we suggest that anti-degree preference and consumption promotion can make distribution more equal. This provides an effective and practical way to optimize the equality of wealth distribution.
